Abstract:	近年來GPS之地球科學應用日益蓬勃發展，目前世界上最新近的應用為監測地震前地球表面上空90-20000公里高之電離層電子含量異常變化。中央氣象局目前建立有上百個GPS連續觀測站，觀測台灣地殼變動與斷層活動。本研究計畫之目的為引進電離層全電子含量計算技術，並且發展統計方法分析GPS觀測資料，用以監測台灣地區地震前電離層全電子含量異常現象。 Recently, the global positioning system (GPS) has broad applications in geosciences. The latest application is to detect anomalies of the total electron content (TEC), ranging from 90 to 20,000 km altitude, over an earthquake epicenter. The Central Weather Bureau (CWB) has set up hundreds of GPS receivers to monitor land deformation and seismicity. This project is to introduce computing technique and develop statistical methods to identify and monitor pre-earthquake anomalies in GPS TEC in Taiwan. 研究期間：9401 ~ 9412
